Over-voltage protection circuit energises. Check the output voltage tht comes out of its SMPS section to main board. If this voltage is more than/less than normal, this kind of fault can occur.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

SONY T.V. MODEL KV-25ST12 4TIMES BLINKS STANDBY


Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505. Check the vertical output IC, especially to the solder terminals for any loose soldering points. Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window.

Red blinking light, SONY KV-32FS13


The 4 blinks usually mean a vertical deflection problem. If you can solder you should be able to repair this yourself. Let me know if you wish to attempt the repair and I'll provide more details and instructions.

Tv wont turn


The blinking red light at the the front of the television is the "Diagnostic STANDBY/TIMER LED".
This little red light will blink 2, 4, or 5 times and then stay off for three-seconds. And blink again for 2, 4, or 5 times. This cycle repeats. The most common diagnostic code is the 4-blink code.

When the red LED blinks 4-times, it means one of two possible causes:
1) +13V is not supplied on the A-board. Or, 2) IC502 is faulty.

It is best to take this television set to a repair facility and ask that the +13V power supply be repaired.
The copper tracks and integrated circuit pads are very thin and delicate on the KV-24FV12 circuit board, and will easily lift off of the circuit board, if the incorrect desoldering tool is used. Unless one has a good quality PACE vacuum desoldering unit, one should not attempt to repair the television.
